Application inea :rune a, 192s. serial no. 113.227..

y Thisiinvention relates to improvements in. door latches of vthepivoted bolty type, and

while in its broader aspects the present in vention comprehends a latchwhich mayhave agwide range of utility, it is particularly concerned withpivoted `bolt latches' for -..swinging closure elements. v u Y An objectof the invention is to provide a latchy of this character-.which may becon lo veniently locked against operation, a latch which' isautomaticallyA acting. when ythe closure'V is swung' to, ,a latch ofsimple, practical, construction,y which will be rugged,

durable land eliicient .in use, which may be manufactured with.comparative economy,

`andwhich may be readily applied to a. door orl'other closure element. f

flVith'the abovenoted and otherl objects in. view, the inventionconsists incertain novel features of construction and combina! tions andarrangements offparts, as will be more fully hereinafter sete forth andpointed outr in lthe claims.- The inventionl may. be more fullyunderstood lfrom the `following description in connection Vwith theaccompanying drawings, wherein- Y' y Fig. lis a fragmentary verticalsectional view through a door, with my improved latch attached thereto,the dotted lines indieating Vthe position` of the bolt mechanism whenythe .latch is rocked onits pivot .to dis.- engagev the holtfrom thekeeper. t y v .Fig 2 is a view similar to Fig.1.,.but showing the :latch,locked against pivotal movement. j

Instr-ating a further modified form of latch'.

Figs. 10 and 11l are sectional planv views on the lines-10-1O and 11-11respectively of Fig. 9.' y i. t

Fig. 12 is a view in` outside elevation of the latch of Fig. y9.

- encircling the arm 118 ofthe vthe bolt from the keeper vfrom theoutside c, Fig. 7 is .a lsectional plan view onthe line Referring lirstto the form of doorv latch shown in Figs. 1 to 4, it will be noted thatI have uS-ed the reference character 10 to indicate a closure frame, andthe reference character' 11 to indicate va closure hingedly mounted atone edge (not shown) and adapt-k VServe `as a pivotal mounting for. onearm 18 of the U-bolt 19., :The latching bolt 21 is mounted torockon theend of the arm4 18,` and isengagejd by the other arm. 20 of the Ubolt19.

i A keeper21 in the'nature of an L-shapedV brack'etjis secured to thekframe 10, and is engageable in a notch 22 in tlie'lower-edge of the bolt21a. A coiled torsional spring 23.

against the intermediate portion of said bolt and maintains the pivotedbolt 21 spring pressed .into engagement with the keeper 21a.

It will befnoted that the bolt 21 is formed at its inner endwithacamming face 24 which enga-ges with the keeper 21a Vto ele-- vate theinner end of the holt as the 'door is swung to closed position, and whenlthe keeperhas. cleared the notch 22, the boltwill be spring pressedinto .its latching position. li`l1`us,thev bolt latches automatically asthe door isswung to closed position.

AFor effecting manual disengagement of' of the door, the outer end ofthe bolt is prol vldedwith a handleV member 25 facilitating the manualrocking of the bolt on its pivot 18. Means are also provided forselectively locking the bolt againstpivotal movement and consequentlylocking the door to the. frame. This meansiincludes a fork 26 intefgralwith a plate 27 and offset therefrom. Platef27 islpivotedatns lowerend to the bottom ofthe outer escutcheon plate 13 as indicated at 28,and when swung yfrom the position .of Fig.. 1 to the positionfofF ig.2,V the yfork26 straddles vthe' outer-end of-the which register with aU-bolt 19 bears bolt closely adjacent an opening 29 therein. Y

By passing the hasp 30 of a padlock 31 through the opening 29, such haspwill entrage with the itorlt to prevent pivotal movement o'l the holt2l.

ln Fins. 5 to 8 inclusive, l have illustrated a slight modification ofthe latch in which di lierent means are utilized for sprint;l pressingthe latch into engagement with its lieepcr and tor locking' thelatchiney holt against pivotal movement. 'Referring non' to theseligures, the pivoted holt 35 extends through aligned slots in the doorll, and the inner and outer eseuteheon plates 3G, il?. ',llhe holt ispivoted on a screw 25S which ei;- tends across the slot in the door. Theinner end ot the holt is notched at 3) toi' engagement with a keeper lllsecured to the :traine lith and the holt sprintT pressed into engagementwith the lceeilier o v a coiled con-- tractile sprim;` -lt anchored tothe, outer end oit the holt, and lo a staple or other suitable anchorageli/Z on the outer tace oli the door. llolt operating handles t3 areprovided at both the inner and outer ends ot the holt 35.

The .means` :tor locking` the holt :flg'ainst reciting; movement in thisinstance includes a channel piece let pivoted at to to the holt on the.inside el the door. .idiacent the channel piece` a pair ot openings itare provided in the loolt. lith the channel piece swung; to the positionof Fie'. the shackle t? ot' the padlock Al-S may he conveniently hurlein the lower openinil` Ll@ andnormal operation of the holt may he had.'It however, the channel piece del is swung; through amiroximatelv 90@to the position ot Fig'. 5,

and the shackle ot the padlock shifted into the upper opening' 1GH itwill he seen that the channel meinten' elieetivelv hloclis pivotalmovement ot the holt. Anv attempted roel:- ingr movement thereof totlisenegago it t'roin the heepen causes the shackle of the padlock totorce the channel member against the inner escnteheon plate.

In Fifi t] to l2 inclusive l have Aillustrated a :turther modilicationot" the invention, in which the holt 5t) is in the nature ot arelativelv wide plate rocking); in aligned slots till in the door 'iland the inner and outer escnteheon plates In this instance `the eulcheon plates are connected liv a U-liolt ou the intermediate portionot which overlies the outer tace o'l the outer eseutcheon plate, and thelegs of which pass through the inner escutcheon plate ind are retainedhv nuts 35. The intermediate portion ot the U-holt passes through anopening; 55 in the latch 5t) and servesI as a pivot therefor.

A coiled cont actile sp1-ingr at 5T to the inside olf the door andengaged at 5S with the inner portion ot the latch 5t), urges the latchinto engagement with a keeper 59 secured to the traine l0. Oper- Ganchored ating` handles (30 and (3l. are |.n'ovided at the inside andontside ot the latch. In order to loch the latch against pivotalmovement, it is merely neces-'sari' to pass the shackle G2 olf a padlochtil througth an opening (lll in the lower edge ol" the outer end olf thelatch :30. This padlock engages the escutcheon plate o?) to preventmovement ot the latch about its pivot tiet, ln the l'orm ot theinmiitions previtmsly deserihed. the slots in the esentcheon plates univserve as au etiective stop to limit the springt pressed movement ot thelatehinfg holt when the holt is not engaged with the lieeper. ln theitorm shown in li`ief.-1. t) to 12, cross pins T5 secured to the latchengage the escutcheon plate to limit the spring; pressed movement of theholt when the door opened.

lllhile l have shown certain ot the pre- `l'erred emhodimentiii o'l theinvention, it will he evident that numerous changes and alterations`might he made in the general `form and arrangement ot parts describedwithoutdepartine Afrom the invention. llence l. do not wish to limit` invsellA to the details set lforth. het shall consider nrvr-rcl'l' atlivhertv to malte such maneges and alterations as Yfairly tall withinthe spirit and scope, oit the appended claims.

l claim: i

l. The iiomhination with a closure 'trame and a swinging closure, oleseuteheon plates secured to opposite il'aces ol' the closure near the'tree edge ott 'the latter, said escutcheon plates and closure having'alie-ned slots therein, a holt pivoted intermediate its ends andextending' through the slots, a keeper on the trame, spring meansurging' the holt into engagement with the keeper, and means torselectivel)v locking; the holt against pivotal movement, includingl a`lorked element piroted to one oit the eseutcheon plates and adaptedtostraddhi the-holt and he held against movement to inoperative positionhy a padlock i-'hacltle passed through the holt. i A

The combination with a closure frame and a swingingl closure, otescutcheon plates secured to opposite Vfates oit the closure near thetree edite ot the latter, said plates and closure having' aligned slotstherein, a. holt pivoted intermediate its ends and extendingT throughthcslots, a keeper on the trame, spring means urging the holt intoengagement with the li'eeper, and means for selectivel)v locking` theholt against pivotal n'ioveineut including' a padlock hasp passedthrough an opening; in the holt adjacent one ot the eseutcheon plates,and means| asso-` ciated with said eseutehcon plate and coacting withthe shackle to prevent rocking ot the holt.
